Entering the new stage of high-quality development，considering the harmonious coexistence of human and nature and the appeal of high-quality urban living environment，urban ecological quality is a profound reflection of the values，targets and elements of urban environment construction in the past. It is also a necessary way to comprehensively enhance the city’s soft power. At present，Shanghai is actively participating in the global city competition，it is the inherent need and inevitable trend to build ecological quality that matches the outstanding global city target. Research on the multi-dimensional evaluation standards of ecological quality will help to promote the transformation of urban “indexed ecological construction” to “multi-value integration of urban development”. To this end，this research uses grounded theory to smelt the theoretical knowledge related to urban environment construction in urban ecology，sociology，economics，ethics and human settlements，so as to build a city. The multi-dimensional evaluation standard of ecological quality provides theoretical support. On this basis，centering on the ecological city construction goal of “becoming a benchmark for green，low-carbon and sustainable development of international megacities” proposed in the “Shanghai Urban Plan （2017-2035）”，a NICEST-based city will be constructed. The multi-dimensional evaluation standard framework for ecological quality includes one goal，six standards and 18 elements，in order to provide a scientific reference for evaluation and management for the improvement of Shanghai’s urban ecological quality，and to promote the improvement of Shanghai’s urban ecological soft power through evaluation and promotion. Comprehensive competitiveness of the city.
